WATER-PIPE.

Specification of Letters Patent.

Patented Dec. 13, 1910 Application filed June 13, 1910. Serial No.566,618.

To all whom it may concern:

Be it known that I, DANmL ALTON, of the town of Strathcona, in theProvince of Alberta, Canada, have invented certain new and usefulImprovements in ater-Pipes, of which the following is the specification.

My invention relates to water pipes and the object of the invention isto provide a wire Wound and coated wooden pipe which will be cheap inconstruction and which will retain the coating or covering materialintact under the ordinary conditions of wear, both in transportation andservice.

The construction of the invention will be fully described herein anddefined in the appended claim, in connection with the accom panyingdrawings which form a part of this specification.

In the drawings Figure 1 is a side elevation of my pipe a portionthereof having been torn away to expose the construction. Fig. 2 is anend View of the pipe. Fig. 3 is an end view of the pipe in a reversedposition to that shown in Fig. 2. Fig. 4 is a longitudinal verticalsectional view through the 1 e. p In the drawings like characters ofreference indicate corresponding parts in each figure.

The pipe consists in a body portion 1 formed from tongue and groovedinterlocking wooden members 2 and a coupling 3 which is placed over thebody portion 1 and is also formed from tongue and grooved wooden members4. After the coupling 3 has been placed over the end of the body portion1 both the body portion and the coupling are spirally wound withreinforcing wires 5 which are secured at their ends in any suitablemanner to the pipe, such as by staples. The wire wound pipe is thendipped in an asphalt composition thereby providing an initial coating 6over the wires.

Immediately the pipe is dipped in asphalt the body portion 1 and thecoupling 3 have a flexible material 7 such as burlap wound around themand secured in such position. The pipe is then again dipped in theasphalt so as to provide a further coating 8 around the burlap and thenit is finally rolled in sawdust which appears at the outer face at 9.

I am aware that pipes are at present constructed having a wire windingand a coating of asphalt or some similar composition over the wires, butthe objection to pipes of this class is that if abused in the slightestthey do not retain the asphalt coating placed on them. Consequently thewire when-exposed is free to corrode and the pipe is ultimately damaged.It will be understood that if such pipes be coated with a material whichis hard enough to resist the action of the sun, in other words whichwill not melt, it will chip when the pipes are being transported, andthis is just as serious a detriment as a pipe from which the coating hasrun off when melted.

With a pipe constructed as I have described it is almost impossible toinjure it in transportation as the burlap coverin prevents the asphaltfrom being scrape off, thereby exposing1 the wires. The sawdust protectsthe asp alt from the heat of the sun when the p1pe is exposed.

What I claim as my invention is:

A wire wound wooden water pipe having an initial coating of asphalt, athickness of burlap around the asphalt, a coating of asphalt around theburlap, and a final coatin of sawdust, as and for the purpose specificSi 'ned at Winnipeg, in the Province of Manitoba, this 30th day of May,1910.
